Upgrading iphone

[flybynight]

I'm due to upgrade my iPhone. I've currently got a 3s 16gb, and I'd like to get a 4s. What difference would getting a 32gb make to me? My phone is currently about 80% full, and I'm not inclined to store video clips or big files on it.
I would like to get a 32, but the price is so much more. What do you think? Daft to? Daft not to? (Apologies in advance - I'm so tired that my eyes are burning. If I'm making no sense, that is why...)

Let me ask you this question.

How much more is it and what's the price difference mean to your monthly budget? If it's not going to matter then why not. More storage can never be a bad thing.

However, another way of looking at it is that your memory is like a kitchen bin. The bigger it is, the more crap you will throw in it and having a bigger bin just means you will empty it less frequently.

Both opinions are valid. I'm leaning towards the kitchen bin theory though!
